Abstract

The invention relates to a method for rapidly preparing a carbon material from waste polyester-cotton fabric. Aiming at the condition that the waste polyester-cotton fabric is high in stock, serious in pollution and difficult to recover, the waste polyester-cotton fabric is washed, sterilized, degraded, separated and stripped at high pressure, and is frozen, dried and ground to prepare the carbon material. Meanwhile, byproducts such as terephthalic acid and ethylene glycol are also separated out. The preparation method is advanced in technology, and accurate and detailed in data; the prepared and separated carbon material is powder; the diameters of powder particles are less than or equal to 130nm; the product purity reaches 99.8%; the byproduct terephthalic acid is powder; the diameters of the powder particles are less than or equal to 2 microns; the product purity reaches 99.6%; the byproduct ethylene glycol is a colorless transparent liquid; the product purity reaches 99.3%; the products can be reutilized as chemical raw materials; and the method is a very advanced method for preparing the carbon material and the byproducts employing the waste polyester-cotton fabric.

Description

technical field [0001] The invention relates to a method for rapidly preparing carbon materials by using waste polyester-cotton fabrics, and belongs to the technical field of recycling waste polyester-cotton fabrics and preparing chemical substances. Background technique [0002] Polyester-cotton blended fabric is a fabric woven by blending polyester staple fiber and cotton fiber, most of which are polyester, and the commonly used mixing ratio is 70% polyester and 30% cotton fiber; polyester is based on terephthalic acid and ethylene glycol. Raw materials, high polymers made by esterification and polycondensation reactions—polyethylene terephthalate, synthetically spun to make polyester fibers, cotton fibers are processed from cotton, and the main component is cellulose; Polyester fiber and cotton fiber are blended in proportion to make polyester-cotton blended yarn, and then weaved to obtain polyester-cotton blended fabric. [0003] In the textile industry, polyester-cotto...
